Former C.M. Russell High football star and NFL quarterback Ryan Leaf has been moved from a Lewistown, Mont., treatment center to the Montana State Prison in Deer Lodge, state officials confirmed Thursday.

Leaf, who was sentenced by District Judge Kenneth Neill to a five-year commitment to the Montana Department of Corrections for drug and burglary charges in June, had been in a lockdown drug rehabilitation facility in Lewistown since July 12.

The first nine months of that sentence were to be spent in Lewistown and then he was to transfer to six months in a prerelease center before likely being given supervised community placement for the rest of the five years, according to Great Falls Tribune archives.

However, the Tribune learned Thursday that "the Montana Department of Corrections terminated Leaf from the treatment program and placed him in prison after he was found guilty of behavior that violated conditions of his drug treatment placement," Dawn Handa, regional probation and parole administrator in Great Falls, said in a statement. "The violations included threatening a program staff member."

Marcie Conmy, administrator at Nexus Treatment Center, confirmed that Leaf is no longer at the Lewistown facility.

According to the DOC's Correctional Offender Network Search, Leaf's status last changed Jan. 10, and it lists his current location as the reception unit at the Montana State Prison.

The treatment program is for methamphetamine treatment or any other addiction with a co-occuring disorder, Conmy said.
